Embodiment: the present invention is done further explanation below in conjunction with accompanying drawing:
As shown in Figure 1, the present invention provides a kind of wind-driven generator, and said wind-driven generator mainly comprises wind wheel 9, support body 1, generator 4 and the circuit 7 that is connected with generator 4; Said generator 4 is arranged on the support body 1, and the input shaft end of generator 4 is provided with input crank 11; The output axle head of generator 4 is provided with generator output crank 5; As shown in Figure 7, said input crank 11 is exactly the handle vertical with the input shaft of generator 4; Said wind wheel 9 is movably arranged on the support body 1 through rotating shaft 14, that is to say that rotating shaft 14 can rotate on support body 1, and wind wheel 9 is arranged on an end of rotating shaft 14; The other end of rotating shaft 14 is provided with wind wheel output crank 12, and is as shown in Figure 4, the handle that so-called wind wheel output crank 12 is just vertical with rotating shaft 14; And the wind wheel output crank 12 in the described rotating shaft 14 is connected with the input crank 11 of generator 4; So just formed wind wheel 9 and rotated the mechanism that drives generators 4 operations, and because between wind wheel 9 and the generator 4 through wind wheel output crank 12 with import crank 11 and be connected, and with respect to generator 4; Input crank 11 just is perpendicular to the handle of the input shaft of generator 4; So, when input crank 11 rotates, just form between the input shaft of input crank 11 and generator 4 with a labour-saving lever construction; So will reduce the loss of energy in mechanically operated process greatly, and then improve the generating efficiency of whole wind power generator; Then can be connected between wind wheel output crank 12 in the said rotating shaft 14 and the input crank 11 of generator 4 through connecting rod 15 or bolt.Said wind wheel is as shown in Figure 8, leafy wheel construction, and this structure can further increase utilization ratio of wind energy, can certainly adopt other common wind wheel structures.
In addition, as shown in Figure 5, in said rotating shaft 14, also be provided with flying wheel 3; So that when wind wheel 9 rotates, increase inertia, increase work efficiency, increase utilization ratio of wind energy.
Two above generators 4 are set in the said wind-driven generator, and as shown in Figure 6, the output axle head of generator 4 is provided with generator output crank 5; The generator output crank 5 of the generator 4 that is connected with wind wheel output crank 12 is connected with the input crank 11 of another generator 4; The input crank 11 of other generators 4 all is connected to the generator output crank 5 of last generator 4, forms the structure of many generator 4 end-to-ends.Shown in Figure 9 is input crank structure on the generator input shaft; Shown in Figure 10 is the generator Structure schematic representation.This wind-driven generator can adopt asynchronous wind driven generator, dual-feed asynchronous wind power generator or directly driving type AC permanent-magnet synchronous generator.
Like Fig. 2, shown in 3 and 4; Generator 4 is four; The output shaft of each generator 4 is provided with a generator output crank 5; Generator output crank 5 on the output shaft of said generator 4 flexibly connects all and between the input crank 11 on the input shaft of next generator 4, and also is to be connected through connecting rod or bolt between input crank 11 and the output crank 12; That is to say that first generator 4 is connected with wind wheel 9; The input crank 11 of second generator 4 is connected with the generator output crank 5 of first generator 4, and the input crank 11 of the 3rd generator 4 and the generator output crank of second generator 45 flexibly connect, and the generator output crank 5 of the input crank 11 of the 4th generator 4 and the 3rd generator 4 flexibly connects; Thereby form the form of four generator end-to-ends; In the whole wind power generator, be exactly to carry out work between a plurality of generators 4, when reducing energy loss so through the input crank 11 and the form of generator output crank 5 this lever transmissions; Further increase work efficiency; Compare with the wind-driven generator of in the past monomotor, if the diameter of wind wheel 9 is 40 meters between 47 meters the time, the general rated output power scope of original wind-driven generator is between 600 kilowatts to 750 kilowatts; And wind-driven generator of the present invention; Through facts have proved that the rated output power scope can be brought up between 1000 kilowatts to 1200 kilowatts, wind energy utilization can improve 10-15%.And if when adopting the form of four generators 4, then the rated output power scope can be brought up near 2200 kilowatts, wind-driven generator so of the present invention phase specific power more in the past can improve 1-2 doubly.If the rotor diameter of wind-driven generator of the present invention is further increased, then power can further strengthen; Be applied in the MW class power generation system and can further improve generating efficiency equally, the utilization of wind energy is further improved.As shown in Figure 2, the bottom of support body 1 is provided with on the bearing 11, so just can guarantee the normal operation of wind wheel.Said support body 1 can be according to the quantity of the generator 4 that is provided with; According to pattern shown in Figure 1 support body 1 is divided into and the corresponding dividing plate of the quantity of generator 4; For example when four generators 4 are set, four dividing plates just can be set, generator 4 be separately positioned on the dividing plate separately get final product then; Certainly, several generators 4 are set and all need the rotating shaft 4 that an independent dividing plate is used for supporting wind wheel 9.
Simultaneously, in the wind-driven generator of the present invention between generator and the generator, between generator and the wind wheel; All flexibly connect through crank, form the form of lever transmission, such Connecting format type of belt drive is more in the past compared; Because lever is laborsaving lever, so in the process of transmission, the loss of energy belt is more in the past compared; Much smaller, so also improved the efficient of work greatly.
Generator of the present invention can be connected to electrical network or be connected to electric storage means 6 simultaneously through circuit 7; So when providing and promptly using electric energy for industry, agricultural, transportation and other all trades and professions; Also can carry out electric energy storage, utilize in the time of in order to the electric energy deficiency.
